IDENTI-FISH echo display
With connection of a IDENTI-FISH
™
compatible transducer, you can distinguish
between swim bladder fish and swim-bladderless fish on the IDENTI-FISH
™
echo
display. The echo displayed in reddish-brown has a swim bladder (herring), and
the echo displayed in light-blue-to-blue does not have a swim bladder (mackerel).
The combination of the IDENTI-FISH
™
graph (see section 2.2) and the IDENTI-
FISH
™
echo display is useful for distinguishing fish species.
Note: The setting of [External IDENTI-FISH Echo Window], which is set during in-
stallation of the system, enables or disables display of the IDENTI-FISH
™
echo
display on a sub monitor. See your dealer for details.
